Infrastructure model collaboration via state distribution

ABSTRACT

A method and system provide the ability to asynchronously collaborate on a model of an infrastructure project. The model is acquired and view settings for the model are captured. The view settings include a feature highlight that provides display attributes/settings for objects and/or features of the model, a camera position providing second settings relating to a camera view of the model, and a data view providing third settings regarding a view of the model data. The view settings are associated with a link. The link is transmitted/provided from a sender to a recipient. The link enables rehydration of a live model based on the captured view settings thereby presenting a state and view settings of the model specified by the sender.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates generally to computer-aided design (CAD)application collaboration, and in particular, to a method, apparatus,and article of manufacture for enabling a designer to share a point intime of a model of an infrastructure project.

2. Description of the Related Art

When design decisions for a model are being made, in a collaborativesetting, there is the need to communicate why the decision is beingmade. In other words, there is a need to communicate and share, withcollaborators, anything that might be used to drive the design decision.To communicate the information, a designer would need to have someone athis or her desk (at the time the decision is made) to see the samecircumstances for the design decision. Prior art systems fail to providea dynamic method to convey/communicate such information while allowing auser to further manipulate and work with/in the model thereafter.Instead, prior art systems tend to share views of the model that arestatic such as renders, images, or video. While static versions may behelpful, they fail to provide the ability to inspect and interrogate thedesign problem in the live model. Accordingly, what is needed is amethod and system that enables users to share a point in time of a modelof an infrastructure project.

SUMMARY OF THE INVENTION

Embodiments of the invention overcome the problems of the prior art byallowing a designer to remotely and asynchronously share a point in timeof a model of an infrastructure project with all of the sameenvironmental settings captured including what features are visible,what kinds of analysis have been running, etc.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description, reference is made to the accompanyingdrawings which form a part hereof, and which is shown, by way ofillustration, several embodiments of the present invention. It isunderstood that other embodiments may be utilized and structural changesmay be made without departing from the scope of the present invention.

Overview

Embodiments of the invention capture a state of a model, with all of theenvironmental settings, including the position in the model, and thefeatures that were being used by the designer. The captured state isembed into a shareable link (e.g., a uniform resource locator/identifier[URL/URI]) and/or entity that is distributed/transmitted to one or moreusers. The shareable link/entity can then be used (e.g., bydownstream/receiving users) to open the model within the context of thedesigner's captured model state. The downstream/receiving users can thenfurther explore the model and investigate other issues around the designproblem in real time in actual model space.

Hardware Environment

FIG. 1 is an exemplary hardware and software environment 100 used toimplement one or more embodiments of the invention. The hardware andsoftware environment includes a computer 102 and may includeperipherals. Computer 102 may be a user/client computer, servercomputer, or may be a database computer. The computer 102 comprises ageneral purpose hardware processor 104A and/or a special purposehardware processor 104B (hereinafter alternatively collectively referredto as processor 104) and a memory 106, such as random access memory(RAM). The computer 102 may be coupled to, and/or integrated with, otherdevices, including input/output (I/O) devices such as a keyboard 114, acursor control device 116 (e.g., a mouse, a pointing device, pen andtablet, touch screen, multi-touch device, etc.) and a printer 128. Inone or more embodiments, computer 102 may be coupled to, or maycomprise, a portable or media viewing/listening device 132 (e.g., an MP3player, IPOD, NOOK, portable digital video player, cellular device,personal digital assistant, etc.). In yet another embodiment, thecomputer 102 may comprise a multi-touch device, mobile phone, gamingsystem, internet enabled television, television set top box, or otherinternet enabled device executing on various platforms and operatingsystems.

In one embodiment, the computer 102 operates by the general purposeprocessor 104A performing instructions defined by the computer program110 under control of an operating system 108. The computer program 110and/or the operating system 108 may be stored in the memory 106 and mayinterface with the user and/or other devices to accept input andcommands and, based on such input and commands and the instructionsdefined by the computer program 110 and operating system 108, to provideoutput and results.

Output/results may be presented on the display 122 or provided toanother device for presentation or further processing or action. In oneembodiment, the display 122 comprises a liquid crystal display (LCD)having a plurality of separately addressable liquid crystals.Alternatively, the display 122 may comprise a light emitting diode (LED)display having clusters of red, green and blue diodes driven together toform full-color pixels. Each liquid crystal or pixel of the display 122changes to an opaque or translucent state to form a part of the image onthe display in response to the data or information generated by theprocessor 104 from the application of the instructions of the computerprogram 110 and/or operating system 108 to the input and commands. Theimage may be provided through a graphical user interface (GUI) module118. Although the GUI module 118 is depicted as a separate module, theinstructions performing the GUI functions can be resident or distributedin the operating system 108, the computer program 110, or implementedwith special purpose memory and processors.

In one or more embodiments, the display 122 is integrated with/into thecomputer 102 and comprises a multi-touch device having a touch sensingsurface (e.g., track pod or touch screen) with the ability to recognizethe presence of two or more points of contact with the surface. Examplesof multi-touch devices include mobile devices (e.g., IPHONE, NEXUS S,DROID devices, etc.), tablet computers (e.g., IPAD, HP TOUCHPAD),portable/handheld game/music/video player/console devices (e.g., IPODTOUCH, MP3 players, NINTENDO 3DS, PLAYSTATION PORTABLE, etc.), touchtables, and walls (e.g., where an image is projected through acrylicand/or glass, and the image is then backlit with LEDs).

Some or all of the operations performed by the computer 102 according tothe computer program 110 instructions may be implemented in a specialpurpose processor 104B. In this embodiment, the some or all of thecomputer program 110 instructions may be implemented via firmwareinstructions stored in a read only memory (ROM), a programmable readonly memory (PROM) or flash memory within the special purpose processor104B or in memory 106. The special purpose processor 104B may also behardwired through circuit design to perform some or all of theoperations to implement the present invention. Further, the specialpurpose processor 104B may be a hybrid processor, which includesdedicated circuitry for performing a subset of functions, and othercircuits for performing more general functions such as responding tocomputer program 110 instructions. In one embodiment, the specialpurpose processor 104B is an application specific integrated circuit(ASIC).

The computer 102 may also implement a compiler 112 that allows anapplication or computer program 110 written in a programming languagesuch as C, C++, Assembly, SQL, PYTHON, PROLOG, MATLAB, RUBY, RAILS,HASKELL, or other language to be translated into processor 104 readablecode. Alternatively, the compiler 112 may be an interpreter thatexecutes instructions/source code directly, translates source code intoan intermediate representation that is executed, or that executes storedprecompiled code. Such source code may be written in a variety ofprogramming languages such as JAVA, JAVASCRIPT, PERL, BASIC, etc. Aftercompletion, the application or computer program 110 accesses andmanipulates data accepted from I/O devices and stored in the memory 106of the computer 102 using the relationships and logic that weregenerated using the compiler 112.

The computer 102 also optionally comprises an external communicationdevice such as a modem, satellite link, Ethernet card, or other devicefor accepting input from, and providing output to, other computers 102.

In one embodiment, instructions implementing the operating system 108,the computer program 110, and the compiler 112 are tangibly embodied ina non-transitory computer-readable medium, e.g., data storage device120, which could include one or more fixed or removable data storagedevices, such as a zip drive, floppy disc drive 124, hard drive, CD-ROMdrive, tape drive, etc. Further, the operating system 108 and thecomputer program 110 are comprised of computer program 110 instructionswhich, when accessed, read and executed by the computer 102, cause thecomputer 102 to perform the steps necessary to implement and/or use thepresent invention or to load the program of instructions into a memory106, thus creating a special purpose data structure causing the computer102 to operate as a specially programmed computer executing the methodsteps described herein. Computer program 110 and/or operatinginstructions may also be tangibly embodied in memory 106 and/or datacommunications devices 130, thereby making a computer program product orarticle of manufacture according to the invention. As such, the terms“article of manufacture,” “program storage device,” and “computerprogram product,” as used herein, are intended to encompass a computerprogram accessible from any computer readable device or media.

Of course, those skilled in the art will recognize that any combinationof the above components, or any number of different components,peripherals, and other devices, may be used with the computer 102.

FIG. 2 schematically illustrates a typical distributed/cloud-basedcomputer system 200 using a network 204 to connect client computers 202to server computers 206. A typical combination of resources may includea network 204 comprising the Internet, LANs (local area networks), WANs(wide area networks), SNA (systems network architecture) networks, orthe like, clients 202 that are personal computers or workstations (asset forth in FIG. 1), and servers 206 that are personal computers,workstations, minicomputers, or mainframes (as set forth in FIG. 1).However, it may be noted that different networks such as a cellularnetwork (e.g., GSM [global system for mobile communications] orotherwise), a satellite based network, or any other type of network maybe used to connect clients 202 and servers 206 in accordance withembodiments of the invention.

A network 204 such as the Internet connects clients 202 to servercomputers 206. Network 204 may utilize ethernet, coaxial cable, wirelesscommunications, radio frequency (RF), etc. to connect and provide thecommunication between clients 202 and servers 206. Further, in acloud-based computing system, resources (e.g., storage, processors,applications, memory, infrastructure, etc.) in clients 202 and servercomputers 206 may be shared by clients 202, server computers 206, andusers across one or more networks. Resources may be shared by multipleusers and can be dynamically reallocated per demand. In this regard,cloud computing may be referred to as a model for enabling access to ashared pool of configurable computing resources.

Clients 202 may execute a client application or web browser andcommunicate with server computers 206 executing web servers 210. Such aweb browser is typically a program such as MICROSOFT INTERNET EXPLORER,MOZILLA FIREFOX, OPERA, APPLE SAFARI, GOOGLE CHROME, etc. Further, thesoftware executing on clients 202 may be downloaded from server computer206 to client computers 202 and installed as a plug-in or ACTIVEXcontrol of a web browser. Accordingly, clients 202 may utilize ACTIVEXcomponents/component object model (COM) or distributed COM (DCOM)components to provide a user interface on a display of client 202. Theweb server 210 is typically a program such as MICROSOFT'S INTERNETINFORMATION SERVER.

Web server 210 may host an Active Server Page (ASP) or Internet ServerApplication Programming Interface (ISAPI) application 212, which may beexecuting scripts. The scripts invoke objects that execute businesslogic (referred to as business objects). The business objects thenmanipulate data in database 216 through a database management system(DBMS) 214. Alternatively, database 216 may be part of, or connecteddirectly to, client 202 instead of communicating/obtaining theinformation from database 216 across network 204. When a developerencapsulates the business functionality into objects, the system may bereferred to as a component object model (COM) system. Accordingly, thescripts executing on web server 210 (and/or application 212) invoke COMobjects that implement the business logic. Further, server 206 mayutilize MICROSOFT'S TRANSACTION SERVER (MTS) to access required datastored in database 216 via an interface such as ADO (Active DataObjects), OLE DB (Object Linking and Embedding DataBase), or ODBC (OpenDataBase Connectivity).

Generally, these components 200-216 all comprise logic and/or data thatis embodied in/or retrievable from device, medium, signal, or carrier,e.g., a data storage device, a data communications device, a remotecomputer or device coupled to the computer via a network or via anotherdata communications device, etc. Moreover, this logic and/or data, whenread, executed, and/or interpreted, results in the steps necessary toimplement and/or use the present invention being performed.

Although the terms “user computer”, “client computer”, and/or “servercomputer” are referred to herein, it is understood that such computers202 and 206 may be interchangeable and may further include thin clientdevices with limited or full processing capabilities, portable devicessuch as cell phones, notebook computers, pocket computers, multi-touchdevices, and/or any other devices with suitable processing,communication, and input/output capability.

Of course, those skilled in the art will recognize that any combinationof the above components, or any number of different components,peripherals, and other devices, may be used with computers 202 and 206.

Embodiments of the invention are implemented as a software applicationon a client 202 or server computer 206. Further, as described above, theclient 202 or server computer 206 may comprise a thin client device or aportable device that has a multi-touch-based display.

Software Embodiments

Designers commonly explore various design options. During thisexploration, a designer may turn on/off certain model applicationanalysis and/or features. For example, a designer may turn on sun shadowanalysis for a certain time of day, and/or may turn on line of sightanalysis. In addition, the designer may have buildings and tree layershidden, and may be using a particular version of the model.

The designer may desire input from another designer (e.g., at adifferent location) about a design problem found. To acquire such input,embodiments of the invention provide the ability for the user to forwarda link/entity to other designers. The link/entity captures thecontextual state of the model application and the model. Upon openingthe link/entity, the recipient is able to view exactly the same state ofthe model, with all of the environmental settings, including theposition in the model, with the features that were active by theoriginal designer turned on, and the features the recipient was usingturned off. Thereafter, the receiving designer can further explore themodel and investigate other issues around the design problem in realtime in actual model space so there is no coordination needed to set upthe design review, nor is it static.

In embodiments of the invention, the link/entity includes/identifies thecamera position, the features turned on/off, analysis results,navigation information, markup/comment information, etc. Thus, insteadof sharing something that is static or may look different due to adifferent application environment setup, all participating collaboratorscan view the state of the infrastructure model from the perspective ofthe originating designer and may continue to work with and manipulatethe model thereafter.

To enable the transmission of the model state, embodiments of theinvention may utilize an infrastructure model that is database drive(e.g., the INFRAWORKS 360™ modeling application available from theassignee of the present application). The elements from within thedatabase are used to populate the link/entity that is shared/distributedto the collaborating users. For example, in the INFRAWORKS 360application, a scenegraph (or elements of the scenegraph) representing amodel may be distributed.

The different elements of the state that are captured may includeversion control (that represents history and time), analysis results(that represents results of an analysis [e.g., an analysis to determinestructural problems in a bridge design]), application settings (thatrepresent user preferences), etc. Once the link/entity is received, thereceiving collaborator may utilize the link/entity to bring up the modelin the state defined by the link/entity.

FIG. 3 illustrates an entity diagram for the differententities/attributes/elements that may be captured/transmitted to arecipient in accordance with one or more embodiments of the invention.In the center, the base entity/element 300 is that of the view settingsat/for a decision point. In other words, at the point where a user wouldis going to make a decision, he/she may view the settings (e.g., thatare about to be transmitted or have already been transmitted to therecipient).

The four categories 302-308 provide/identify theentities/elements/categories whose state can be captured. Such fourcategories include feature highlights 302, camera position 304, dataviews 306, and in-canvas highlights 308.

The feature highlights 302 are elements/settings for objects/features ofthe model. Feature highlights 302 include information such as objectionisolation settings 310 (e.g., which objects have been isolated fromother elements/objects for editing/viewing), tool icons 312 (e.g., thetool icons that are displayed), object explode settings 314 (e.g., whichelements of one or more objects are exploded in order to view componentelements such as the layer name, color, line type, etc.), andmeasurement tool results 316 (e.g., results from using the measurementtool to compute/view the distance between two points/objects).

The camera position 304 includes the position of the camera 318 (e.g.,the viewing frustum and angle), camera paths/camera path settings 320 (adefined path [e.g., key frames, the speed to move between key frames,transitions, etc.] taken by a camera to view/simulate a view/model overtime), and the scene graph level of detail 322 that is displayed.

The data views 306 include underlay selection 324 (e.g., settingsdetermining whether an element contained in an underlay is selectable),data panels 326 (e.g., settings for a data panel that provides access toproject files and folders), data layers 328 (e.g., settings for whethereach layer in the model is on/off, coordinate system settings, etc.),and analysis results 330 (e.g., results from an analysis such as aheating and cooling loads analysis, solar studies, display styles andview settings for the analysis results, etc.). As used herein, anunderlay is a file/image that is similar to an attached raster image inthat it provides visual content but may not actually be part of thedrawing file itself, but is linked to the drawing file through a pathname. Underlay files are often reproductions of their source drawing,are not as precise as drawing files, and may show slight discrepanciesin precision.

The in-canvas highlights 308 include comments 332, annotations 334, andstoryboard 336 settings (e.g., camera height, regular or largestoryboard view options, size of thumbnails, etc.).

FIGS. 4A-4J illustrate an exemplary collaboration workflow between twousers that perform various changes/analysis of an infrastructure projectmodel and asynchronously share a point in time of the model inaccordance with one or more embodiments.

In FIG. 4A, on an interactive webpage that enables a view of a 3D model,a first user, Brett, determines there is a need to bring the materialcost of the building 402 back in line with the budget. Accordingly,Brett initiates the option to change the material cost 404.

In FIG. 4B, the material of the building 402 has been changed and thedisplay illustrates a cost reduction 406. Further analysis shows thechange is a good decision for the material cost and the schedule.

In FIG. 4C, Brett decides to send the results to his colleague Melissafor review. As illustrated, the “share with” dialog window 408 includesan identification of the recipient, Melissa 410, and the selectable link412 (to the captured features/elements utilized when Brett changed thebuilding material).

FIG. 4D illustrates the recipient view. On the recipient's device 414(e.g., a mobile phone), the message/request 416 received by Melissa fromBrett is displayed. The deep link URL 412 rehydrates the view from whichBrett was making design decisions (e.g., from FIGS. 4A and 4B).

In FIG. 4E, the same metrics, tools, and analysis results 418 that Brettwas reviewing (e.g., in FIGS. 4A and 4B) are shown to Melissa on herdevice 414, so that they can collaborate with a common understanding,without screen sharing, and in a live model rather than a view orphotograph. The deep linking enables/provides access to the key factorsimpacting the design decisions that were made and allows for furtherexploration and analysis.

In FIG. 4F, Melissa wants to understand the impact outside just thematerial cost and the schedule—she wants to understand the overallimpact. Accordingly, the options for running an energy analysis 420 anda sun shadow/sunlight analysis 422 are activated/selected.

In FIG. 4G, Melissa has elected to run the energy analysis 420 and thesun shadow analysis 422. The analysis results (of analysis run by bothBrett and Melissa) are displayed in area 418 and show that the long termcost is actually greater.

In FIG. 4H, Melissa has opted to share 424 these results back with Brettfor his review.

FIG. 4I illustrates the recipient view on Brett's device (e.g., in a webpage), where Brett receives the notification 426, and can follow thedeep link 428 to rehydrate the view sent by Melissa.

FIG. 4J illustrates the recipient's (Brett's) view after following thedeep link. The view sent by Melissa is rehydrated and Brett can learnabout the further analysis Melissa created.

Logical Flow

FIG. 5 illustrates the logical flow for asynchronously collaborating ona model of an infrastructure project.

At step 502, the model of the infrastructure project is acquired.

At step 504, view settings for the model are captured. As describedabove with respect to FIG. 3, the view settings may include numeroussettings/attributes. View settings may provide (1) a feature highlightthat includes display attributes/settings for objects and/or features ofthe model; (2) a camera position that includes second settings relatingto a camera view of the model; and (3) a data view that includes thirdsettings regarding a view of the model data.

The feature highlight may include an object isolation setting thatdetermines which objects have been isolated from other elements/objects,a tool icon, an object explode setting that determines which elements ofthe objects are exploded in order to view component elements, or ameasurement tool result that provides a result from using a measurementtool to compute/view a distance between two points/objects.

The camera position may include a camera position view, a camera path,or a scene graph level of detail.

The data view may include an underlay selection identifying an underlayimage that is selected, wherein the underlay image provides visualcontent but is not part of a drawing file that represents the model. Thedata view may further include a data panel that provides data panelsettings for a panel that provides access to project files and folders,a data layer for data layer settings for each layer in the model, or ananalysis result consisting of results from performing an analysis of themodel.

The view settings may further include an in-canvas-highlight forexposing user-defined emphasis of the model. Such an in-canvas highlightmay be a comment, an annotation, or a storyboard.

Further to the above, the view settings may also include a modificationto the model made by the sender.

At step 506, the view settings are associated with a link.

At step 508, the link is transmitted/provided from a sender to arecipient. The link enables rehydration of a live model based on thecaptured view settings thereby presenting a state and view settings ofthe model specified by the sender (i.e., the same settings/circumstancesthe sender used when making a design decision).

CONCLUSION

For example, any type of computer,such as a mainframe, minicomputer, or personal computer, or computerconfiguration, such as a timesharing mainframe, local area network, orstandalone personal computer, could be used with the present invention.

In summary, embodiments of the invention provide the ability tocollaborate on a model design by capturing, into a link/entity, thestate of an infrastructure model desired by a user, and sharing such alink/entity with other users who can activate the link/entity toreplicate the model state. Thus, an exact state of an infrastructuremodel that has caused concern or needs review by others isreturned/provided. There is no guesswork in setting up the space forreview by a collaborator because the state is passed in the link/entity.Further, the state is live and not static such that additional analysiscan be made, comments submitted, etc., from the same point of view asthe original designer.
